During the hydrometallurgical treatment of complex sulphide ores, the dissolution of useful minerals can be carried out by electrochemical oxidation. Compared to classical chemical and oxidation-reductions, potentiostatic electrochemical oxidation has several advantages and in particular that of controlling the reactions. Thus, the comparison of the electroreactivity of pyrite and of chalcopyrite in chloride acidic medium allows the choice of the best conditions for selective dissolution of the chalcopyrite starting from pyritic samples.Lors du traitement hydrométallurgique des minerais sulfurés complexes cuprifères, la solubilisation des minéraux utiles peut être effectuée par oxydation électrochimique.
